what type of pointe shoes are those? also, as a dancer and pointe shoe fitter at the dance store that I work at, may I suggest that next time you should sew your ribbons at the highest point of your arch. Do you not use elastic? I've also found that heating the edge of the ribbons with a flame (not in the flame itself, but next to it) without burning it but slightly melting some of the man-made elements in the satin helps keep it from fraying
